Seems our friends at BMW are ramping up to place some BMW Performance Products on the 09 Sedan. I ran across this video today. Couple of things I noticed where the new wheels, new front spoiler, new rear apron, and what looks like a Big Brake Kit.
The other thing that was interesting to me was the fact that it looks like this Performance Kit is on a 328i and not the higher-end 335i.
Enjoy the video
